JC3303 光話機/光源一體機主機是聚測公司研制的新一代智能光儀表,廣泛應用于數(shù)字數(shù)據(jù)網(wǎng),電信網(wǎng)和有線電視等光纖線路工程的施工、檢測、維護及光纖衰減測量,可實現(xiàn)單纖雙向全雙工通信,通話品質(zhì)高,不會因為距離遠近而有所不同使用,無需用戶設定,當講話雙方接線相連,話路隨即自動建立,并有大屏幕及LED指示,使用戶非常容易使用。該新型儀表外觀流暢,手感好,貼心的人性化設計,操作簡單方便,滿足用戶的zui大需求。
產(chǎn)品特色:
1.具有單纖全雙工通信模式,數(shù)字和模擬混合調(diào)制
本光話機是利用空閑光纖作話音通信的光機,使用數(shù)字和模擬混合調(diào)制,使語音通話非常清晰流暢。
2.大動態(tài)范圍:45dB
3.長距離通話:120km
4.自動建立連接功能
當光話機接入光纖鏈路中,自動檢測及建立一個通話
5.具有頻率光調(diào)制光源功能。
光源可以發(fā)出連續(xù)光及270Hz、330Hz、1KHz、2KHz的調(diào)制頻率光(TONE),頻率光一般用于光纖的識別。
